G'day. Installing an equaliser is a half measure, but helps account for the stock head unit, and you can taylor the sound. Personally I will probably just end up with a complete Alpine head unit in the tissue area, but for now the Eq will do.
The stock head unit has line out speaker wires. These need to be converted to RCA for nearly all Eq / Amps. Line converters are available from Jaycar, but apparently the go are the Stinger SLOC2's from JB hifi .About $50 each. This will convert the stock head speaker wires to RCA to plug into an Equaliser or remote amp. Problem from there is the Equaliser usually has RCA out, so you then have to go the whole Auxillary amp thing for the speakers, rewiring etc. If you don't want to go that far, find an equaliser with line in and out, but try and find a name brand such as an older Alpine or Clarion etc. Cheap Equalisers are horrilbe at best. Mine is a soundstream 4 band EQ which is ideal as it splits the signal into fronts, rears, and a sub. There is also a sub control knob.
In order of things to do.
1. Get some decent 5x7 for the front. Alpine, Infinity, Boston if you can afford it. Money spent here gives the biggest sound return. Read the caraudioaustralia forums and look into sound deadening the doors and sealing the holes to make the doors a "box".
2. Add in an equaliser if you feel you need more control. This is a difficult area to do well. I've spent a bit of money there, and a decent head unit isn't that much more.
3. Upgrade to a 4 way amp and upgrade the rear parcel shelf speakers, but spend the money on the fronts, the rears are just fill. I'd reckon the stock sub and Ford amp would be OK for normal use. If you want more, you need to get a sub signal ( which I did with the EQ ) or via a decent head unit, again I like Alpine, but most good sets have a sub out as well. You'll then go the more expensive route of a sub amp and a sub in a box. Perhaps just upgrading the free air sub in the parcel shelf with a better free air sub or similar would be the cheapest way out, but you'd want to deaden the parcel shelf with some bitumen sheeting, dynamat, or stuff from Jaycar if you want to do it cheaper. Speakers mounted onto bitumen sheets give much better response, check out the dynamat sheets at a sound shop for the idea. I believe the stock sub is a cheaper pioneer unit, made in Japan.
For fords I have heard great things about Eclipse, Alpine and Boston speakers, Soundstream and Phoenix Gold amps ( Kicker too ) and the SLOC2's for conversion. Other amps don't apparently filter the alternator noise from the poverty stock head unit, which is a pain in the butt at best.
Enjoy the ride, it just gets more and more expensive each time. My current set up has gone stupid, but I can't wait to finish it.
